Unit Tests window

View | Tool Windows | Unit Tests
Alt+8

This window lets you manage all your unit testing activities in different tabs.

To search tests, start typing a test name or its CamelHumps abbreviation as soon as your focus is in this window.

Explorer tab

Using this tab, you can explore and run/debug unit tests of all supported frameworks in the entire solution. Note that unit tests from a project only appear in the tab after the project is built. Tests from currently opened files are updated automatically, new tests from the opened files appear in the unit test explorer as soon as you create them.

Unit Test Explorer displays tests from the entire solution

When the Explorer tab, or any unit test session tab is open, you can use the following controls on the left-hand toolbar:

Toolbar Controls

Control	Name	Description
	Run Unit Tests `Ctrl+U, R`	Runs selected tests. To select multiple texts, click them holding the `Ctrl` key.
	Debug Unit Tests `Ctrl+U, D`	Debugs selected tests in the current session.
	Cover Unit Tests	By clicking this button, you can start code coverage of the selected tests. Currently, .NET code-coverage features are available only on Windows.
	Profile Unit Tests	By clicking this button, you can profile selected tests. Currently, .NET code-profiling features are available only on Windows.
	Run Unit Tests under dotMemory Unit `Ctrl+U, M`	Runs selected tests tests with dotMemory Unit enabled. Use this button to run tests that use dotMemory Unit framework check code for memory issues.
	Append Tests to Session `Ctrl+U, A`	Click this button to add the selected tests to a test session. JetBrains Rider will suggest choosing one of the existing sessions or creating a new one.
	Grouping	Allows grouping items in the window by different categories.
	Expand All/ Collapse All `Ctrl+NumPad Plus`/ `Ctrl+NumPad Minus`	Expands/collapses all nodes in the current tab.
	Previous/ Next `Ctrl+Alt+Up` / `Ctrl+Alt+Down`	Navigate to the previous/next item and scrolls through the source code accordingly.
	Unit Test Settings	Opens the Build, Execution, Deployment \| Unit Testing page of JetBrains Rider settings, where you can configure all settings related to unit testing.

Unit test sessions tabs

These tabs appear each time you run tests from the current document or from the project or solution. For every new combination of tests (unit test session), a new tab opens.

These tabs are designed to help you run any number of unit test sessions, simultaneously and independently of each other. Sessions can be composed of any combination of tests. In the debugging mode, only one session can be run at a time.

The unit test tree shows the structure of tests belonging to a session, which you can filter to show only passed, failed or ignored unit tests. You can navigate to the code of any unit test by double-clicking it.

A unit test session displayed in the Unit Tests window

When a unit test session tab is open, you can additionally use the following controls on the upper toolbar:

Toolbar Controls

Control	Name	Description
	Repeat Previous Run `Ctrl+U, U`	Repeats the previous test run.
	Rerun Failed Tests `Ctrl+U, F`	Starts execution of tests that failed in the previous run.
	Run Current Session `Ctrl+U, Y`	Runs all tests in the current session.
	Run Unit Tests `Ctrl+U, R`	Runs selected tests. To select multiple texts, click them holding the `Ctrl` key.
	Stop Execution	Stops the current test session.
	All Tests	Show all tests in the current test session.
	Passed Tests	Only show successful tests and hide all other tests.
	Failed Tests	Only show failed tests and hide all other tests.
	Ignored Tests	Only show ignored tests and hide all other tests. A test is ignored if it has the corresponding attribute, or if the whole category where it belongs is ignored.
	Inconclusive Tests	Only show inconclusive tests. A test is considered inconclusive if it was started but JetBrains Rider could not read the test runner output. This could be a sign of an error occurring in the test runner.
	Show Time	Allows you to show or hide execution time for each item.
	Toggle Output Position	Use this button to change the position (right or bottom) of the output pane, which lets you analyze test results and navigate from a failed test's output to the code lines that originated the assertion or exception.
	Options	You can configure this set of preferences individually for each test session. Build Policy — Specifies whether building is required before executing tests. Provides several options: Automatic (selected by default) — Before executing tests, JetBrains Rider will rebuild all projects that are related to the current test session and that have changes since the last execution. Whole Solution — Before executing tests, JetBrains Rider will rebuild all projects in your solution that have changes since the last execution. Never — JetBrains Rider will not build anything before executing tests. If you choose this option, you will have to make sure that all related projects are built. Lock Session — Locks the current test session to prevent automatically adding new tests to this session. Platform Type — Lets you explicitly specify platform architecture of the test runner or choose Automatic to use platform architecture corresponding to the project settings. Diagnostics — Click this button to open the log of the last executed test session.

Title bar context menu and buttons

You can right-click on the window title bar and use the context menu to configure its viewing mode, associate the window with a different tool window bar, or resize and hide the window.

You can also use the toolbar buttons:

Item	Shortcut	Description
		Click this button to access a subset of the context menu commands that let you configure window's viewing mode.
	`Shift+Escape`	Use this icon or shortcut to hide the tool window. When used in combination with the `Alt` key, clicking this icon hides all the tool windows attached to the same tool window bar.
